The Federal Aviation Administration on Sunday issued an emergency airworthiness directive for immediate or step-up inspections of aircraft similar to a fire in Denver this weekend.
The order includes some Boeing 777 airplanes equipped with Pratt & Whitney PW4000 engines and “that would mean some airplanes would be removed from service,” FAA Administrator Steve Dixon Said in a statement.
The order came on Saturday after a United Airlines passenger jet powered by two Pratt & Whitney PW4000 engines suffered a furious mid-air engine failure for an emergency landing.
Were also No reports of injuries In the suburban Broomfield, where vast tracts of engines and debris landed on yards, parks and vehicles.
Dixon said a preliminary review of the incident showed that “inspection gaps should be extended to hollow fan blades that are unique to this model of engine on Boeing 777 airplanes,” Dixon said.
United is the only US operator in its fleet with the PW4000 engine type.
